About This Chapter
Combustion Reactions & Energy - Chapter Summary
In these lessons on combustion reactions and energy, you can review how to write and balance combustion reactions. You can also gain a clearer understanding of how activation energy relates to a reaction's energy, and the rate of a chemical reaction. By the end of the chapter, you should be positioned to:
- Discuss signs and evidence of chemical change
- Explain endothermic and exothermic reactions
- Analyze energy with a reaction coordinate diagram
- Define combustion reaction
- Describe slow, spontaneous, and explosive combustion reactions
- Recall the effect of catalysts on rates of reaction
- Discuss the effect of temperature on the rate of a chemical reaction
- Describe how to prevent pollution from combustion of organic compounds
These easy-to-comprehend lessons can help you better understand combustion reactions and energy in little time. You can review all the lessons in order, or just look at the ones that cover the topics you need to review. A brief quiz is available for each lesson to test your knowledge.
1. Chemical Change: Signs & Evidence
From fireworks to a rusty penny, a lot of what we see involves a chemical change. Explore this lesson to learn about five different signs or evidence of chemical changes.
2. Endothermic and Exothermic Reactions
Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.
3. Analyzing Energy With a Reaction Coordinate Diagram
In this lesson, we will learn about reaction coordinate diagrams and how they help us analyze energy in reactions. We will learn what the graph means and how to interpret it.
4. Combustion Reaction: Definition & Examples
Chemical reactions occur every day. Some of them are quite useful to us. In this lesson, you will learn about chemical reactions that are known as combustion reactions.
5. Writing and Balancing Combustion Reactions
Discover what a combustion reaction is as well as what reactants are needed and what products are produced. Learn to write and balance a combustion reaction. Through the concepts of bond energies, learn how to explain why combustion reactions are largely exothermic.
6. Slow, Spontaneous & Explosive Combustion Reactions
In this lesson, you will learn about three types of reactions: slow, spontaneous, and explosive combustion reactions. Examples of each type of reaction will also be discussed.
7. Activation Energy and Catalysts
Learn how to define activation energy and how it relates to a reaction's energy. Learn what an activated complex is and where it fits into an activation energy diagram. Discover how a catalyst works to change the activation energy of a reaction and what this means to metabolism in the body.
8. Rate of a Chemical Reaction: Modifying Factors
Why are some reactions much faster than others? Is it possible to change how fast a reaction occurs? In this lesson, you will learn what the rate of a chemical reaction is. You will also discover how factors such as temperature, concentration, surface area, and catalysts impact reaction rates.
9. Effect of Catalysts on Rates of Reaction
In this video lesson, we will learn how catalysts speed up chemical reactions. We'll also discuss how catalysts are used in industry and consider the catalysts in our own bodies. A short quiz will test your new knowledge.
10. Rate of a Chemical Reaction: Effect of Temperature
Learn how temperature affects reaction rates. Discover the rate law as well as how the Arrhenius equation relates to the rate law and predicts the effect of temperature on the rate of reaction.
11. Pollution from Combustion of Organic Compounds: Causes & Prevention
Organic compounds contain hydrogen, oxygen, carbon, and often times other elements. In this lesson, we will discuss why the burning of these compounds causes pollution and steps that can be taken to prevent this pollution.
